Gravity in a warped 6D world with an extra 2D sphere
Akira Kokado, Takesi Saito
Corrections to Newton's inverse law have been so far considered, but not clear in warped higher dimensional worlds, because of complexity of the Einstein equation. Here we give a m…
New Mixing Angles in the Left-Right Symmetric Model
Akira Kokado, Takesi Saito
In the left-right symmetric model neutral gauge fields are characterized by three mixing angles between three gauge fields , which…
A Solvable Model for Fermion Masses on a Warped 6D World with the Extra 2D Sphere
Akira Kokado, Takesi Saito
In a warped 6D world with an extra 2-dimensional sphere, we propose an exactly solvable model for fermion masses with zero mode. The warp factor is given by …
Closed Superstrings in a Uniform Magnetic Field and Regularization Criterion
Akira Kokado, Gaku Konisi, Takesi Saito
We summarize exact solutions of closed superstrings in a constant magnetic field, from a view point of the regularization criterion. Some models will be excluded according to this…
Noncommutative Quantum Mechanics and Seiberg-Witten Map
Akira Kokado, Takashi Okamura, Takesi Saito
In order to overcome ambiguity problem on identification of mathematical objects in noncommutative theory with physical observables, quantum mechanical system coupled to the NC U(1…
Hall Effect on Noncommutative Phase Space
Akira Kokado, Takashi Okamura, Takesi Saito
When phase space coordinates are noncommutative, especially including arbitrarily noncommutative momenta, the Hall effect is reinvestigated. A minimally gauge-invariant coupling of…
